Objective: To study about attitude and knowledge regarding basic-life-support among college students outside medical
system.
Material and Method: The cross-sectional study in the emergency department of Thammasat Hospital. The authors included college students at least aged 18 years old and volunteers to be study subjects. The authors collected data about attitudes and knowledge in performing basic-life-support by using set of questionnaires.
Results: 250 college students participated in the two hours training program. Most of participants (42.4%) were second-year college students, of which 50 of 250 participants (20%) had trained in basic-life-support program. Twenty-seven of 250
participants (10.8%) had experience in basic-life-support outside the hospital. Most of participants had good attitude for
doing basic-life-support. Participants had a significant improved score following training (mean score 8.66 and 12.34, respectively, p<0.001). Thirty-three of 250 participants (13.2%) passed the minimum score before trained testing, whereas 170 of 250 participants (68%) passed the minimum score after trained testing.
Conclusion: With accurate knowledge and experience, lay rescuers may have more confidence to perform basic-life-support to cardiac arrest patient. The training program in basic-life-support has significant impact on knowledge after training.
